Improvement in lamp-burners



A'UNITED STATES PATENT FFICE.

PHILANDEB BAKER, OF CHICAGO, ILLINOIS.

IMPROVEMENT IN LAM P-BURNERS.

Specification forming part of Letters Patent No. 81,128, dated August18, 1868; antedated August 5, 1868.

To all whom it may concern:

Be it known that I, PHILANDER BAKER, of Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inLamps; and I do hereby declare and make known that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, and the letters and iigures marked thereon,which form part of this specication.

My said invention consists in attaching the burner of a lamp to thewick-tube, or the screw-cap closing the orifice of the oil-cup, in sucha manner as to be readily removed, so that the lamp'may be fllled, whendesired, without the trouble of unscrewing the cap closing the lamp, orremoving the same in any manner, while, upon replacing the burner, thelamp or oil-cup is eftectually and hermetically closed, as desired.

To enable those skilled in the art to understand how to construct anduse my said invention, I will now proceed to describe the same withparticularity, making reference in so doing to the aforesaid drawings,in which- Figure I represents a side view of my invention; 2, a centralvertical section of the same. Fig. 3 is a plan view of the same, thechimney and cone being removed. Fig. 4 is a top view of the annular ringor plate upon'which the lower end of the chimney rests, and Fig. 5 is adetached side view of the tube through which the oil-cup of the lamp isfilled.

Similar letters of reference in the several gures denote the same partsof my invention.

A represents the body of the lamp, and B isa short tube, provided withscrew-threads upon its lower end to screw into the lamp, as shown.W'ithin this tube B, whose upper end is closed by a partition, d, isarranged the wick-tube, or section of wick-tube C, being supported inthe partition d, as indicated in the drawings.

D represents a short tube fitting or sliding over the tube B, so as tobe removed when desired, to which is attached the annular chimney-rest Eby means of arms E. Upon said chimney-rest are arranged three (two ormore may be used) standards, c, upon whose upper ends is secured aperforatedtplate, F, at the center of which is placed the upper sectionof the wick-tube C', as shown. Upon the perimeter of the said perforatedplate F is arranged an elastic flaring flange, e, slotted,

as shown, over which the end of the chimney is pressed until it restsupon said support E, before mentioned, the said flange e thus serving,by its eXpansibility, to hold the chimney securely in place.

A cone, Gr, is secured upon or over the wick-tube by a rod, g, passingthrough the same, and the lugs j' upon said plate F, or in any othersuitable manner.

It may be observed that the particular mode of connecting or supportingthe upper section of the wick-tube upon the plate upon which the chimneyrests, or which is connected with the tube D, which is herein shown, isnot essential, as any other open connection to avoid the transmission ofthe heat downward to the oil may be used.

In one side of the tube B, which is secured l in the lamp near its upperend, an opening, a, is made, through which the oil may be poured intothe lamp by an ordinary lampller, as desired, upon removing the burnerand the outer tube D attached to the burner, and which covers and closesthe aperture c when the parts are arranged for use.

The chimney may be removed by simpl)r raising it up, as the elasticholder yields automatically.

To prevent the effort to remove the chimney from detaching the burnerand tube D from the tube B, any suitable adjustable device may be usedfor detaining the tube D upon the tube B until said device should be somanipulated as to release it.

Having described the construction and operation of my invention, I willnow specify what I claim and desire to secure by Letters Patent.

I claim- 1. The combination of the tubes B D and, the sectional ordivided Wick-tube C C', ar-
